================================================================================================

Why does so many error occur about snmp library?

I don't find the reason and answer

The only thing i can do is just add below files,

===============================================================================

#include <net-snmp/agent/table_iterator.h>

#include "/home/psyche/sychoi/net-snmp-5.3.2/agent/helpers/table_iterator.c"

#include <net-snmp/library/snmp_client.h>

#include "/home/psyche/sychoi/net-snmp-5.3.2/snmplib/snmp_client.c"

#include <net-snmp/agent/snmp_agent.h>

#include "/home/psyche/sychoi/net-snmp-5.3.2/agent/snmp_agent.c"

=================================================================================

Then I make agentx again... the result is below

Still error remain...

===========================================================================================

[r...@localhost nexlib]# make agentx

ppc_82xx-gcc -I. -I/home/psyche/sychoi/include/libnexcmd -I/home/psyche/sychoi/include -O2 -Dlinux -I. -I/home/psyche/sychoi/install/usr/include -c -o agentx.o agentx.c

ppc_82xx-gcc -I. -I/home/psyche/sychoi/include/libnexcmd -I/home/psyche/sychoi/include -O2 -Dlinux -I. -I/home/psyche/sychoi/install/usr/include snmp_interface.c -o snmp_interface

In file included from snmp_interface.c:17:

/home/psyche/sychoi/net-snmp-5.3.2/agent/snmp_agent.c:1725: error: parse error before '*' token

make: *** [snmp_interface] 锟斤拷锟斤拷 1

============================================================================================

This is snmp_agent.c : 1725

===========================================================================================

void netsnmp_free_agent_snmp_session_by_session(netsnmp_session *sess, void (*free_request)(netsnmp_request_list *))

=============================================================================================

I don't know what is the problem..

I find about "netsnmp_free_agent_snmp_session_by_session" in menual, but i don't find the problem about that

What shall i do?!

I think that this is net-snmp problem.. Isn't it?

If there is anyone know about it, please give me some comment..

Thank you..
